Distinguished Professor: “Time To Retire The Notion Hurricanes Are Slowing Down (Much Less Attribution Claims)”

Climate alarmist scientists refuted

Distinguished climate expert Roger Pielke Jr. tweeted on recent findings contradicting alarmist claims that tropical storms have slowed down (thus stick around longer and wreak more devastation) or are more frequent and intense.

First, lets look at frequency and intensity.

No detected upward intensity/frequency trend at all

In an article appearing at Forbes, Pielke writes together with atmospheric scientist Dr. Ryan Maue how they and University of North Carolina-Wilmington professor Jessica Weinkle used datasets available around the world on tropical cyclones to create a historical record of storms of at least hurricane strength that made landfall.

Fifty years of global landfalls of tropical cyclones of hurricane strength, based on the Saffir-Simpson hurricane scale, were analyzed.

According to the findings published earlier here:

The analysis does not indicate significant long-period global or individual basin trends in the frequency or intensity of landfalling TCs of minor or major hurricane strength. The evidence in this study provides strong support for the conclusion that increasing damage around the world during the past several decades can be explained entirely by increasing wealth in locations prone to TC landfalls, which adds confidence to the fidelity of economic normalization analyses.”

Shown below is an updated chart from the Pielke et al 2012 paper, which was extended to 2019. It shows global tropical cyclone landfalls at hurricane strength from 1970 to 2019:

According to Pielke and Maue at FORBES: “There are a lot of ups and downs in the data, but no obvious trends.”

Tropical storm translation speeds have not slowed down

Pielke also tweeted about a new study appearing in Nature here. The University of Colorado scientist commented:

He added that the claim that tropical cyclones have now slowed down are “supported by both observations and modeling” and that “there is no reason to expect a slowdown” in the future:


The distinguished professor also says it’s: “Time to retire the notion that hurricanes are slowing down (much less the attribution claims).”

    There is a typo in this sentence :

    – “He added that the claim that tropical cyclones have now slowed down are supported by both observations and modeling.”

    It should be “… tropical cyclones haven’t slowed down (their translation speed) …”

    BTW, keep the good work and Happy new year !
